      mediabay shouldn't include <linux/ide.h> unconditionally so
      remove the superfluous include from mediabay.c (<asm/mediabay.h>
      will pull <linux/ide.h> in for CONFIG_BLK_DEV_IDE_PMAC=y).

      ide: Stop disks on reboot for laptop which cuts power · b0aedb04
      Bruno Prémont authored
      
      
      My laptop (Acer Travelmate 660) always cuts the power when rebooting
      which causes the disk to emergency-park it's head.
      
      Add a dmi check to stop disk as for shutdown on this laptop.

      ide-cd: fix kernel crash on hppa regression · a1f9a89c
      Helge Deller authored
      
      
      With 2.6.30-rc2 I face a kernel crash on the 32bit hppa architecture 
      due to ide-cd when udev creates the device nodes at startup:
      
      Kernel Fault: Code=26 regs=8ed34c40 (Addr=00000024)

       [<10116068>] intr_return+0x0/0x4
      
      This crash seems to happen due to an uninitialized variable "rc".
      The compiler even warns about that:
        CC      drivers/ide/ide-cd.o

      /mnt/sda4/home/cvs/parisc/git-kernel/linus-linux-2.6/drivers/ide/ide-cd.c:612: warning: `rc' might be used uninitialized in this function
      
      After applying the trivial patch below, which just initializes 
      the variable to zero, the kernel doesn't crash any longer:
      
      Starting the hotplug events dispatcher: udevd.
      Synthesizing the initial hotplug events...

      done.

      palm_bk3710: UDMA performance fix · db2f38c2
      David Brownell authored
      
      
      Fix UDMA throughput bug:  tCYC averages t2CYCTYP/2, but the code
      previously assumed it was the same as t2CYCTYP.  (That is, it was
      using just one clock edge, not both.)  Move the table's type
      declaration so it's adjacent to the table, making it more clear
      what those numbers mean.
      
      On one system this change increased throughput by almost 4x: UDMA/66
      sometimes topped 23 MB/sec (on a drive known to do much better).  On
      another system it was around a 10% win (UDMA/66 up to 7+ MB/sec).
      
      The difference might be caused by the ratio between memory and IDE
      clocks.  In the system with large speedup, this was exactly 2 (as a
      workaround for a rev 1.1 silicon bug).  The other system used a more
      standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch
      might have some issues, they're not unheard-of.
